Like other digital music players, iPods can serve as external data storage devices. Storage capacity varies by model, ranging from 2 GB for the iPod Shuffle to 128 GB for the iPod Touch (previously 160 GB for the iPod Classic, which is now discontinued).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What's the storage capacity for the iPod Touch?
128 GB
